Specification of Letters Patent.

Application filed April 20, 190s. Serial No, 428,024.

Patented Dec. 15, 1908.

To all whom it may concern: Be it known that I, FRANK G. HELD, of E Kenyon, Goodhue county, Minnesota, have i invented certain new and useful Im rovements in Litter-Carriers, of which the ollow- 1 ing is, a specification. T he ob'ect of my invention is to provide a carrier apted to run on a cable and designed for transporting stable manure and l refuse-from the stable to'a distant dumping point.

A further object is to provide means whereby all danger of the carrier wheels jumping'the cable through oscillation or vibration, is prevented.

The invention consists generally in various constructions and combinations, all as here inafter described and'particularly pointed out. in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side Fig. 2 is a detail sectional view illustrating the locking mechanism. 1* 1g. 3 i

. is a detail view of the lock or latch mechanism showing the position of the parts when 1 the carrier is released. Fig. 4 is a detail sectional view showing the manner of su porting the carrier on the wheel hangers. ig. is a detail view illustrating a modified form of locking latch. Fig. 6 is a detail sectional view of the same.

In the drawing, 2 represents a cable upon which the carrier is sus ended; The trip 3 is adjustable on the cab e by means of a. cam i lever 4. In the position shown in Fig. '1 the trip is locked on the cable, but by swinging the cam lever downward it will release its grip on the cable and the trip may be moved to some other point thereon. 5 represents the carrier or bucket having gudgeons 6 that are journaled in barsfi that are adjustab'ly connected withthe ends of a bail 7b'* means of holes 7 and bolts 7". This bai is provided with a truss strap Sand carrier wheels 9 are adapted to rest on the cable 2 and have hanger spindles 10 that are movable within holes in the strap 8 and the bail 7 and are he strap 8 and the bail are connected with i a series of bolts 12 and are held in paralle relation by sleeves 13 and 14. A fork 154s carried by one of. said bolts and straddles the middle of the bail and a rocker or'equalizing bar 16 that is provided with a rier will automatically dump itself.

the bail and has holes in its ends to receive the spindles 10.

The rocker bar has a limited vertical movement and is guided in the fork 15 between the bail and a pin 17 mounted in the lower end of the fork. The bail is adapted to rock on said bar and accommodate itself to the oscillations or vibrations of the carrier without danger of disturbing the wheels in their travel on the cable. Generally in devices of this kind any jerk or sudden shock to the carrier, as in startingor stopping it, will be communicated to the ,wheels and cause them to jump the cable. With the mechanism heretofore described, however, all danger of this kind is avoided. The collars 11 are provided with ribs 18 that are adapted to enter recesses 19 in the ends of the rocker bar. This is to hold the wheels in linewhen run ,ning on a straight track and to allow a Si ht rotary movement of the wheels'and spind es, elevation of a litter carrier embodying my invention.

the purpose of locking it in position to re-.

ceive its load I provide a pin 20 on one end of the carrier adapted to snap into a hole 21 provided in a spring plate 22 that is secured to one end of the bail 7 above its pivot. This plate has arms 23 that act as guides to engage the pin 20 and direct it into the hole 21. A curved lever '24 is pivoted on the bail and has an arm to extend across and bear on the spring plate 22 so that when pressure is a plied tosaid lever the springplate will 0 llattened as'indicated in Fig. 3, and disengaged from the pin 20, whereupon the car- For the purpose of operating the lever 24 I provide a cam lever :25 pivoted on -a bracket 26 and havinga flat face 27 that is adapted to contact with the lever 24 and lock it in position to hold the spring plate out of-engagement with the locking pin 20. The cam-lever 25 is operated by means of a link 28 that is connected to one end of a lever 29 pivoted at 30 on the bail 7 and having an anti-friction roller 31 in'position to engage the trip 3 at a predetermined point on the cable. When the cam lever is tilted its flat surfacewillbe.

In Fig. 5 I have shown a modification the elevated track.

locked at the desired point on the track and the znitel'riction roller 31 coming in contact notch. 2&3 in a lever 3d that IS pivoted at on one end of the bail. This lever normally is l. :ld by gravity in the path of the latch 32. its con nection with the lever 29 is the same as shown in Fig. l.

in the operation of the device the bucket being swung into position to receive its lead is locked by the engagement of the pin it; with the spring iillcd the op n'ator pushes the carrier out on The trip device 3 is therewith will cause the lever 29 to be oscillated to tilt the cam lever in and swing the lever 2 t outwardly to disengage the spring plate from the locking pin, whereupon the buclret will swing bottom side up with the weight of the load and discharge its contents. By providing the equalizing bar arrangement 1 am able to direct the carrier around. the curves and on switches without danger of the wheels leaving the track.

As illustrated in Fig. 1, I may mount springs 10 on the spindles 10 between the rocker bar 16 and the bail. These springs yieldin 'ly resist the operation of the bar. These springs may be made oi any degree of stiilness and in place of them i may substitute sleeves or collars which will hold the rocker bar rigid and prevent its oscillation.

p The use of these sleeves being so obvious l have thought detailed illustration unnecessary as the device with the sleeves would be in ei'lect a rigid carrier head.

I claim as my invention 1. The combination, with an elevated track,- of a carrier bucket, a bail'therefor, hangers having wheels adapted to travel on said. track, and spindles loosely connected with said bail, and an equalizing bar having a central rocker bearing on said bail and conneeted on each side of said bearing with said spindles, for the purpose specified.
